There is also a certain scorn for visual languages, because there are hardly any good general purpose languages and there are few developers specializing in the areas where specific ones are most useful. So visualization tools are often confused with them and derided for it.
However, when a good visual tool for programming it is universally adopted, and like what happens with the AI paradox, no longer considered a visual tool (see syntax highlighting, "intellisense" autocomplete, inspect expressions at debugging, file minimaps and function trees...)
() There are some excellent visual tools for software inspection, but they tend to be proprietary and/or tied to a single language or having their own IDE (e.g. see Sourcetrail), so they can't be easily generalized or integrated with other standard development tools, so they get limited usage.
